Thanks for the feedback! Going to make some changes to the website to reflect that later today! Right now we support connecting Google Doc, Google Sheet, PDFs from Google Drive, Slack channel, or Confluence space. O365, Notion and a couple other sources integrations are in beta. We don't technically have restrictions on volume, the biggest customers we have have around 100 GB of data with us total. If you were trying to connect a terrabyte worth of data, that might be a conversation about pricing! :)
